— Pierre Joseph ProudhonContext: Communism is inequality, but not as property is. Property is the exploitation of the weak by the strong. Communism is the exploitation of the strong by the weak. In property, inequality of conditions is the result of force, under whatever name it be disguised: physical and mental force; force of events, chance, fortune; force of accumulated property, &c. In communism, inequality springs from placing mediocrity on a level with excellence. This damaging equation is repellent to the conscience, and causes merit to complain; for, although it may be the duty of the strong to aid the weak, they prefer to do it out of generosity, — they never will endure a comparison. Give them equal opportunities of labor, and equal wages, but never allow their jealousy to be awakened by mutual suspicion of unfaithfulness in the performance of the common task.
Communism is oppression and slavery. Man is very willing to obey the law of duty, serve his country, and oblige his friends; but he wishes to labor when he pleases, where he pleases, and as much as he pleases. He wishes to dispose of his own time, to be governed only by necessity, to choose his friendships, his recreation, and his discipline; to act from judgment, not by command; to sacrifice himself through selfishness, not through servile obligation. Communism is essentially opposed to the free exercise of our faculties, to our noblest desires, to our deepest feelings. Any plan which could be devised for reconciling it with the demands of the individual reason and will would end only in changing the thing while preserving the name. Now, if we are honest truth-seekers, we shall avoid disputes about words.
Thus, communism violates the sovereignty of the conscience, and equality: the first, by restricting spontaneity of mind and heart, and freedom of thought and action; the second, by placing labor and laziness, skill and stupidity, and even vice and virtue on an equality in point of comfort. For the rest, if property is impossible on account of the desire to accumulate, communism would soon become so through the desire to shirk.

— Pierre Joseph ProudhonContext: Of what consequence to you, reader, is my obscure individuality? I live, like you, in a century in which reason submits only to fact and to evidence. My name, like yours, is truth-seeker. My mission is written in these words of the law: Speak without hatred and without fear; tell that which thou knowest! The work of our race is to build the temple of science, and this science includes man and Nature. Now, truth reveals itself to all; to-day to Newton and Pascal, tomorrow to the herdsman in the valley and the journeyman in the shop. Each one contributes his stone to the edifice; and, his task accomplished, disappears. Eternity precedes us, eternity follows us: between two infinites, of what account is one poor mortal that the century should inquire about him?
Disregard then, reader, my title and my character, and attend only to my arguments.
Ch. I: "Method Pursued in this Work. The Idea of a Revolution"

— Pierre Joseph ProudhonContext: If I were asked to answer the following question: What is slavery? and I should answer in one word, It is murder, my meaning would be understood at once. No extended argument would be required to show that the power to take from a man his thought, his will, his personality, is a power of life and death; and that to enslave a man is to kill him. Why, then, to this other question: What is property! may I not likewise answer, It is robbery, without the certainty of being misunderstood; the second proposition being no other than a transformation of the first?
I undertake to discuss the vital principle of our government and our institutions, property: I am in my right. I may be mistaken in the conclusion which shall result from my investigations: I am in my right. I think best to place the last thought of my book first: still am I in my right.
Ch. I: "Method Pursued in this Work. The Idea of a Revolution"

— Pierre Joseph ProudhonContext: All my economic ideas as developed over twenty-five years can be summed up in the words: agricultural-industrial federation. All my political ideas boil down to a similar formula: political federation or decentralization.
Du principe Fédératif [Principle of Federation] (1863)

— Pierre Joseph ProudhonContext: Tormented by conflicting feelings, I appealed to reason; and it is reason which, amid so many dogmatic contradictions, now forces the hypothesis upon me. A priori dogmatism, applying itself to God, has proved fruitless: who knows whither the hypothesis, in its turn, will lead us?
I will explain therefore how, studying in the silence of my heart, and far from every human consideration, the mystery of social revolutions, God, the great unknown, has become for me an hypothesis, — I mean a necessary dialectical tool.
Introduction

— Pierre Joseph ProudhonContext: I have made every effort to obtain exact information, comparing doctrines, replying to objections, continually constructing equations and reductions from arguments, and weighing thousands of syllogisms in the scales of the most rigorous logic. In this laborious work, I have collected many interesting facts which I shall share with my friends and the public as soon as I have leisure. But I must say that I recognized at once that we had never understood the meaning of these words, so common and yet so sacred: Justice, equity, liberty; that concerning each of these principles our ideas have been utterly obscure; and, in fact, that this ignorance was the sole cause, both of the poverty that devours us, and of all the calamities that have ever afflicted the human race.
